Step‑by‑Step Instructions for Butternut Squash with Brown Butter Hazelnuts
Step 1: Preheat the Oven
Begin your culinary journey by preheating your oven to 425°F (220°C). This high temperature is essential for achieving beautifully caramelized butternut squash. While the oven warms up, gather your ingredients and prepare the baking sheet by lining it with parchment paper to prevent sticking and ensure easy clean-up.
Step 2: Prepare the Butternut Squash
Next, take your peeled and cubed butternut squash and place it in a large mixing bowl. Drizzle with extra-virgin olive oil and sprinkle with kosher salt and ground black pepper to taste. Toss the squash until each piece is well-coated, then spread it evenly on the prepared baking sheet, making sure there is space between the cubes for even roasting.
Step 3: Roast the Squash
Pop the baking sheet into your preheated oven and roast the butternut squash for about 35 minutes. Halfway through, take a moment to give the squash a gentle toss with a spatula to ensure even cooking. You’ll know it’s done when the edges are golden brown and the squash is fork-tender, releasing a delightful sweet aroma.
Step 4: Make the Brown Butter
While the squash is roasting, melt your salted butter in a skillet over medium heat. Keep a close eye on it as it cooks, stirring occasionally. In about 3 minutes, the milk solids will turn a beautiful golden-brown, signaling that your brown butter is ready. The nutty scent will fill your kitchen, adding richness to your Butternut Squash with Brown Butter Hazelnuts.
Step 5: Add Aromatics
Once your butter is browned, stir in the chopped hazelnuts, minced garlic, and fresh thyme leaves. Let this mixture cook for an additional minute until the garlic is fragrant and the hazelnuts are toasted. Remove the skillet from heat, allowing the aromatic brown butter sauce to meld beautifully with the nutty flavors.
Step 6: Assemble the Dish
With your butternut squash roasted to perfection, transfer it to a serving platter. Gently spoon the savory brown butter hazelnut mixture over the squash, ensuring even coverage for those rich flavors. For an added touch of color and tartness, sprinkle pomegranate arils on top, creating a stunning dish that’s sure to impress your guests.

Make Ahead Options
These Butternut Squash with Brown Butter Hazelnuts are perfect for busy home cooks looking to save time during the week! You can cube and toss the butternut squash in olive oil, salt, and pepper up to 24 hours in advance, then store it in an airtight container in the refrigerator. Additionally, prepare the brown butter hazelnut sauce, allowing it to cool completely before refrigerating for up to 3 days. To finish the dish, simply roast the squash as directed, reheat the browned butter mixture in a skillet, and combine them together just before serving. This prep will ensure that your dish is just as delicious and saves you precious time when it comes to meal planning!

Expert Tips for Butternut Squash with Brown Butter Hazelnuts

Butternut Squash with Brown Butter Hazelnuts Recipe FAQs
What’s the best way to select a butternut squash?
Look for a butternut squash that feels heavy for its size and has a smooth, tan-colored skin. Avoid any with dark spots or blemishes, which can indicate overripeness. A firm and unblemished squash is key to achieving that sweet, creamy flavor when roasted.
How should I store leftovers of the roasted butternut squash?
Store any leftovers in a sealed container in the refrigerator for up to 3 days. Before serving, simply reheat in the microwave or oven until warmed through. For best results, I recommend enjoying the dish fresh, but it can definitely be stored to savor later!
Can I freeze the butternut squash with brown butter hazelnuts?
Absolutely! To freeze, make sure the dish is completely cooled, then transfer it to an airtight container or specially designed freezer bag. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge and reheat gently in the oven at 350°F (175°C) for about 10 minutes to restore some of that delightful crunch!
What if my hazelnuts end up soggy?
If you find your hazelnuts have lost their crunch, a quick fix is to briefly roast them in the oven at 350°F (175°C) for about 5-7 minutes, or on the stovetop over medium heat, stirring frequently until they crisp up. This adds warmth and enhances their flavor, transforming your dish back into a crispy delight!
Are there any dietary considerations for this recipe?
While this recipe is naturally vegetarian and gluten-free, be mindful of nut allergies. If you’re serving to those with allergies, you can substitute the hazelnuts with seeds like pumpkin or sunflower for a similar crunch. For those watching their butter intake, consider using a plant-based margarine to maintain that rich brown butter flavor with a vegan twist.
Can I add other vegetables to this dish?
Absolutely! For a heartier version, consider tossing in other vegetables like carrots or brussels sprouts alongside the butternut squash. Just ensure that they are cut to similar sizes for even roasting. Adding a mix can provide different textures and add even more flavor to this butternut squash with brown butter hazelnuts recipe!
